The tibial plate includes a medial fossa, a lateral fossa, a post insertable into the opening, a third sliding surface which the first sliding surface contacts at a posterior surface of the post, and a fourth sliding surface which the second sliding surface contacts behind the post. The artificial knee joint is configured to move in a first sliding state in which the first sliding surface is in contact with the third sliding surface, or a second sliding state in which the second sliding surface is in contact with the fourth sliding surface, according to a flexion angle.
